Abstract
The invention concerns a method for operating an internal combustion engine () having a plurality of combustion chambers (), in the case of which the combustion chambers () are charged with fuel and air or with a fuel/air mixture. In order to prevent torque jumps from occurring when cylinders () of the internal combustion engine () are shut down and when switching the operating mode of direct-injection internal combustion engines (), it is proposed that the charging of the combustion chambers () with fuel and air or with a fuel/air mixture be controlled individually via open-loop or closed-loop control for each combustion chamber (). In the case of a direct-injection internal combustion engine (), a certain number of combustion chambers () can be operated with homogenous-charge operation, and the remaining combustion chambers () can be operated with stratified-charge operation in accordance with the level of torque required.
